[英]Bounding box extraction
I am having some trouble with a function I found for generating the xmin, xmax, ymin, ymax located in a .xml
file.我发现 function 用于生成位于
.xml
文件中的 xmin、xmax、ymin、ymax 时遇到了一些问题。 I am not sure why is it not working and I feel like it's a simple mistake that I am not considering.我不确定为什么它不起作用,我觉得这是一个我没有考虑的简单错误。
def extract_boxes(self, filename):
# load and parse the file
tree = ElementTree.parse(filename)
# get the root of the document
root = tree.getroot()
# extract each bounding box
boxes = list()
for box in root.findall('.//bndbox'):
xmin = int(box.find('xmin').text)
ymin = int(box.find('ymin').text)
xmax = int(box.find('xmax').text)
ymax = int(box.find('ymax').text)
coors = [xmin, ymin, xmax, ymax]
boxes.append(coors)
# extract image dimensions
width = int(root.find('.//size/width').text)
height = int(root.find('.//size/height').text)
return boxes, width, height
bbs = extract_boxes(r'C:\Users\name\Desktop\kangaroo-master\annots\00001.xml')
---------------------------------------------------------------------------

TypeError: extract_boxes() missing 1 required positional argument: 'filename'
I found the mistake.我发现了错误。 I did not import Element Tree in and needed to remove
self
because I originally pulled the code from a class, but am not using it in a class anymore.我没有将元素树导入并需要删除
self
,因为我最初是从 class 中提取代码,但不再在 class 中使用它。
import xml.etree.ElementTree as ET
def extract_boxes(filename):
# load and parse the file
tree = ET.parse(filename)
# get the root of the document
root = tree.getroot()
# extract each bounding box
boxes = list()
for box in root.findall('.//bndbox'):
xmin = int(box.find('xmin').text)
ymin = int(box.find('ymin').text)
xmax = int(box.find('xmax').text)
ymax = int(box.find('ymax').text)
coors = [xmin, ymin, xmax, ymax]
boxes.append(coors)
# extract image dimensions
width = int(root.find('.//size/width').text)
height = int(root.find('.//size/height').text)
return boxes, width, height
bbs = extract_boxes(r'C:\Users\zlesl\Desktop\kangaroo-master\annots\00001.xml')```
